Inertial Electrostatic fusion can make power at about 5/8 the cost of conventional plants (most is BOP, Balance of Plant costs) process steam at 1/3 the cost of others, make synfuels (ethanol) at less than $0.5/gallon, destroy nuclear waste, and make space engines commercial, etc, etc. The basic physics is summarized in Bussards IAC paper in October, 2006. And in much earlier papers in the early 1990's. All still valid.
